Thanks, but I have brand news. I have just seen (it was too quickly I hadn't been able to read it) that when I try to start jboss it shows an exception which says that "could not start on port 1099 address already in use: JVM_Bind" or something like this. I have looked for the proccess in this port with netstat -aon andto my surprise the palication who is already using this port is java.exe. I have tried to finish but it appears later.

I have been looking with Ccleaner what I have installed about Java and I have:
Java 2 Runtime Environment, SE v1.4.2_11
Java 2 SDK, SE v.1.4.2_11
Java DB 10.4.1.3
Java(TM) 6 Update 10
Java(TM) SE Development Kit 6 Update 10
Java(TM) SE Development Kit 6 Update 3
Java(TM) SE Development Kit 6 Update 7

¿Can I savely uninstall any of them? ¿Which one should I have? I think that perhaps there are 2 JVM running though I think this is impossible.

That is fine. I have about a dozen different JVMs installed on my PC (from 1.3.1 through 1.6.0_10). They will not interfere with each other. Simply set JAVA_HOME to the one you want to use. According to an earlier post you are using 1.6.0_10.

If you want to clean up some room on your hard drive, you can uninstall "Java(TM) SE Development Kit 6 Update 3". If you don't need 1.4.2, you can uninstall it.

I don't see a 1.5.0 version, which makes me believe that you did not try item #4 from one of my prior posts.

OK, I got it from another post of this forum. I had ashampoo installed in the computer and even I had turn it off It interferes. The only way was ininstalling it and it worked.
Thanks to everyone who has been giving ideas. I appreciate it very much.
Just thanks.
